The probability of victim select a particular person `= 1/5`

If all the nine victim select the same person, the probability of that happening is,

`P = (1/5)^9`

`P = 5.17 xx 10^(-7)`

**Therefore there is a very small chance of `5.17 xx 10^(-7)` that all nine victims would select the same person.**
